You may like to keep an eye out for a spring fungus that seems to be doing well this year – Inocybe erubescens, formerly I patouillardii – English name Deadly Fibrecap!.  Being a spring / early summer species and a nice chunky chap, it could be mistaken for St Georges mushroom when young and undamaged, because the characteristic reddening is not usually apparent straight away; see the photo of specimens at different ages.  As regards habitat, it seems to favour beech woods on chalk or limestone, sometimes with white helleborine, and even more  excitingly, occasionally yellow birds nest.
